Cold-Core Tornado

2018-11-29 By Roger Edwards

For years, I had wanted to observe one of the small, often beautiful tornadoes that develop from shallow, fast-moving supercells that develop in arcs of convection, just ahead of a compact middle-upper level low.  Colloquially, they’re called “cold-core” tornadoes, after the swath of cold air aloft that accompanies such cyclones, and that contributes to the instability supporting the supercells.  This day afforded just such an opportunity.  After several non-tornadic supercells, funnels and a brief spinup or two seen farther west in the arc, in North Dakota, this ghostly vortex finally appeared just E of the Minnesota border, not certainly a tornado at first, but most certainly one with time.  The small, ragged updraft area aloft didn’t look like much, but it organized quickly as it moved away from us. 3 SSE Fisher MN (17 Jun 10) Looking NNE 47.7566, -96.7815 RADAR

About

Welcome to SkyPix, an online photo book of clouds, weather and water by Roger Edwards. As in a printed coffee-table book, every image has its own page with a unique story. After all, meaningful photography is much more than just picture-taking; it is visually rendering a moment in place and time from a perspective like none other. As a scientist and an artist, I hope my deep passion for the power and splendor of our skies and waters shines through in these pages. If you are a cloud and weather aficionado, outdoor enthusiast, outdoor or nature photographer, art lover, or anyone who craves learning, enjoy...
